This was the 2nd time in 2 weeks that we had this problem. It gets worse. Later that day, while driving, all the warning lights (traction control, brakes, etc.) came on and the vehicle lost it's brakes. My wife managed to get the car parked safely by pumping the brakes. She turned the car off and back on again and all was normal. She then got the car home without further incident. When I got home, I started up the vehicle and all of the warning lights came on and once again the brakes would not work.

We checked with On Star to see if they recorded any malfunctions, however, their computers were experiencing challenges and they could not give us any information.

We are now waiting to hear from the dealer.
